DRIERFOR CIGARETTE-MACHINES.

Specification of Letters Patent.

Application filed April 5, 1905. Serial No. 253,998-

To all whom, it may concern.-

Be it known that I, NAPOLEON DU BRUL,

a citizen of the United States, residing in Cincinnatnin the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in Driers for Cigarette- Machines, of which the followingis a specification.

Sometimes when cigarettes are madewith great rapidity the seam is notthoroughly dry when the rod emerges from the folding tube, and the seamopens under the internal pressure of the filler; also, when the pasteextends outside the seam and is not thoroughly dry the paste will pickupfragments of tobacco or dust and will cause the severed cigarettes toadhere. Moreover, when the machine is operated in an atmosphere below acertain temperature and the folding-tube is cold it is diflicult tosecure proper adhesion in the pasted joint. For these reasons it hasbeen proposed to embody driers of various forms in cigarette-machines.These driers have heretofore been arranged. as permanent accessories tothe machine and have in some cases consisted in a heating and ironingtube in addition to the ordinary folding-tube. In other cases theheating means is perma nently embodied in the folding-tube. The formerof these two plans is objectionable, because of the additional length ofpassage for the cigarette-rod, and both are objectionable, because theheating action cannot be immediately arrested when the machineisstopped, but remains in contact with the cigarette-rod and endless tapeto the injury of both.

The present invention has for its object to provide an economical andefiective drier of simple construction that may be readily applied toand made to act through the ordi nary folding-tube of acigarette-machine to dry the pasted seam of the cigarette, which may beswung out of effective position and leave the thin folding-tube to coolrapidly during temporary stoppage of the machine or entirely removedwhen not required.

In the accompanying drawings, Figures 1 and 2 are a side and a plan viewof my new heater in use. Figs. 3, 4, and 5 are respectively a verticaltransverse section, a horizontal section, and a bottom plan view of theheater.

A represents a common form of foldingtube by which the paper wrapper ismade to surround the filler in a continuous cigarettemachine and bywhich the edges of the paper wrapper (one of which is previouslysupplied with paste) are made to overlap and adhere.

B represents the heater forming the subj ectmatter of my presentinvention. It is supported on trunnions 5, upon which it may be swung toand from the tube A, with which it conforms and with which it is held inengagement by a catch 0, carried by the upper overhanging portion N.

D represents supporting-brackets for the heater, which may be of anysuitable form required by the particular machine to which the heateristo be applied, and the bearings for the trunnions b are open, so thatthe heater B may be lifted out and removed when its use is not required.When the machine is temporarily stopped and it is desired not to coolthe heater down or to injure the cigarette rod or tape, the heater isgrasped by the handle E and swung backward to the position shown indotted lines in Fig. 3. I

The heater may be heated in any suitable manner. I prefer to use agas-pipe F, discharging into a mixer G, from which the blueflame mixtureis delivered into the basechamber H, whence it escapes to a longitudinalseries of ports I into the peculiarlyfoimed burner-chamber K, Where moreair is supplied through the intakes L and M. The burning gas mixtureplays through the chamber K into the upper chamber N, and the productsof combustion escape through theoutlet 0. A baffle-plate P in thechamber K further assists in mixing the air and forces the burning gasesagainst the wall which it is desired to heat.

I do not limit myself to the particular construction of the interior ofthe heater shown, as this may obviously be varied according to the fuelemployed. Gas is usually obtainable where these machines are inoperation, and for that reason I have illustrated an effectiveconstruction of gasheater.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In combination with a continuous cigarette-machine, having afolding-tube, means movable on the machine to and from the tube forheating said folding-tube to dry the seam of the cigarette rod passingtherethrough.

2. In combination with the folding-tube of I do a continuouscigarette-machine, a heater ap plied to the exterior of saidfolding-tube and movable on the machine into and out of heat ingrelation with the tube for the purpose set forth.

3. In combination with the folding-tube of a continuous cigarettemachineor other tube through which the cigarette-rod passes, a heater movableon the-machine to and from heating relation to said tube, for thepurpose set forth.

4. In combination with a tube through which the cigarette-rod passes, atrunnioned heater movable upon its trunnions to and from a position inwhich it is adapted to heat said tube.

5. In combination with the tube through which the cigarette-rod passes,a trunnioned heater having one wall made to conform to said tube andmovable to and from the same.

6. In combination with the tube through which the cigarette-rod passes,a heater mounted on trunnions by which it is movable to and from thetube, and having a catch releasably holding it in heating relation tothe tube.

7. In combination with a continuous cigarette-machine,supporting-brackets, and a heater for drying the pasted seam of thecigarette-rod, having trunnions upon which it is movable to and fromdrying position, and having said trunnions removably mounted in bearingsin the supporting-brackets, whereby the heater may be wholly removedfrom the machine.

8. A drier for cigarette-111acl1ines, comprising a hollow body ada tedto lie parallel with and conform to the folding-tube of thecigarette-machine, and having a base-chamber into which fuel isdischarged, provided with an upwardly-discharging burner-opening, acombustion-chamber into which said burner-opening discharges, havingsuitable which the products of combustion are dis charged.

9. A drier for cigarette-machines com prising a hollow body adapted toconform to the folding-tube of a cigarette-machine and constructed witha base-chamber for fuel having an upwardly-discharging burner-opening, acombustion-chamber into which said burneropening discharges, havinginlets for air to support combustion, a baffle-plate extendingtransversely of said combustionchamber to deflect the burning gasestoward the wall which contacts with the foldingtube, and an extension tothe combustionehamber extending a part of the length of the drier andoverhanging the folding-tube.

10. In combination with a continuous cigarette-machine, a heatercomprising a lower chamber to which the fuel is admitted and an upperchamber in which the fuel is burned, the said heater being provided withtrunnions and supporting-brackets whereby it is supported in position onthe machine by its own weight onlyv 1 1. The combination with thefolding-tube of a continuous cigarette-machine, of a heater trunnionedin the base portion thereof and having means for the introduction offuel thereto, also in the base portion.

12. In combination with the folding-tube of a continuouscigarette-machine, a heater comprising a means for introducing fuel ator near the base thereof, trunnions at or near the bottom of said heaterand brackets hav ing open grooved ends wherein the trunnions of theheating means may be set in such manner as to be movable into and out ofheating relation with the folding-tube or bodily removed from themachine.

The foregoing specification signed at Cincinnati, Ohio, this 24th day ofMarch, 1905.
